### Path convertor

Using an option directly from Starlette you can declare a *path parameter* containing a *path* using a URL like:

```
/files/{file_path:path}
```

In this case, the name of the parameter is `file_path`, and the last part, `:path`, tells it that the parameter should match any *path*.

So, you can use it with:

## El orden importa

Cuando creas *operaciones de path* puedes encontrarte con situaciones en las que tengas un path fijo.

Digamos algo como `/users/me` que sea para obtener datos del usuario actual.

... y luego puedes tener el path `/users/{user_id}` para obtener los datos sobre un usuario específico asociados a un ID de usuario.

				path := baseDirFromPrefix(prefix)
				filterPrefix := strings.Trim(strings.TrimPrefix(prefix, path), slashSeparator)
				if path == prefix {
					filterPrefix = ""
				}

				lopts := listPathRawOptions{
					disks:          disks,
					fallbackDisks:  fallbackDisks,
					bucket:         bucket,
					path:           path,
					filterPrefix:   filterPrefix,

문서에 매개변수에 경로가 포함되어야 한다는 정보가 명시되지는 않지만 여전히 작동합니다.

### 경로 변환기

Starlette의 옵션을 직접 이용하여 다음과 같은 URL을 사용함으로써 *path*를 포함하는 *경로 매개변수*를 선언할 수 있습니다:

```
/files/{file_path:path}
```

이러한 경우 매개변수의 이름은 `file_path`이며, 마지막 부분 `:path`는 매개변수가 *경로*와 일치해야 함을 명시합니다.

따라서 다음과 같이 사용할 수 있습니다:
